CALENDAR-CLOCK.

SPECIFICATION forming part of Letters Patent No. 231,782, dated August 31, 1880.

7 Application filed April .11, 1880. (No model.)

To all whom it may concern Be it known that I, OTTO F. SCHULTZ, of Louisville, Kentucky, have invented a new and useful Clock-Calendar, of which the following is a specification.

My invention relates to improvements in that class of calendars which are attached to clocks to show the day of the week and the name and day of the month; and it consists, first, in a device for communicating motion at fixed intervals of time from the works of the clock to the calendar attachment; second, in a device for simultaneously registering the day of the week and month; third, in a device for compensating in months of less than thirtyone days; fourth, in a device for adding one day to February in leap year, making the calendar perpetual.

' Figure 1 of the accompanying drawings is a front elevation of my invention, showing its working parts without the front piece of the frame by which some of said parts are supported. Fig. 2 is avertieal section ofmy communicator, the front in Fig. 1 being at the left in'Fig. 2. Fig. 3 is a portion of the calendardial.

n represents the central spindle of a clock 1 carrying a spur-wheel that meshes with a spurwheel, It, of my communicator, the two bearing such ratio that the wheel h is caused to revolve once a day, carrying with it its spindle r by means of a clutch-collar, 7., which is fast to the spindle, and has a spring-pin, l, passing freely into a single hole in the wheel 71, the point of said pin Z and the forward edge of the hole in wheel It being wedge-shaped, so that the spindle r may be turned forward without turning the wheel h, for the purpose of setting the calendar to any day desired without opening its works.

Upon the spindle r is a cam, g, which raises a yoke, and with it the connecting-wire fand the lever B at each revolution. When the flat side of the cam q comes under the yoke 9 said yoke is allowed to fall nntilit rests on the end of the hollow screw 0, which is in the stationary frame of the communicator, and may be set to adjust the fall of said yoke and of the wire j, which passes longitudinally through said screw 0, connecting the yoke wit-l1 its depending lever B and pawl C, so that said pawl shall move the year-disk A, which it engages, one tooth at each motion, which is once a day.

The disk A has in its periphery three hundred and sixty-five teeth, corresponding to the days of a year. The teeth are too small to be shown, a few enlarged ones being indicated at each pawl O and G, the latter pawl being aretainer for the disk A. o

J J are portions of the stationary frame of the calendar, at the righthand top of which the lever B is hung, and from which posts X Y project forward, supporting a front portion of the frame. (Not shown.)

F is a lever swinging on a pivot of the front frame, caused to move forward by a project ing arm, E, connected by a weight, D, to the pawl C, said lever F carrying the pawl e, which engages the day-wheel L, which has thirty-one teeth, I being its retaining-pawl, pivoted to the front frame. The lever F is weighted to draw itself backward, its extreme motion being limited by stop-pins P P.

The curve of contact of lever F with arm E is the result of long experiment, for the purpose of allowing each drop of pawl O into one tooth to move it enough to carry wheel L one tooth. At the end of each month having but thirty days there is a depression in the arc of teeth in the perimeter of the year-wheel which allows pawl O to drop enough to carry wheel L two teeth or days, passing to the first of the next month. These depressed arcs of teeth gradually rise to the circumference of the full circle of disk A in the space of one month.

At the end of February the are is depressed to allow the pawl O to carry forward three days. This depressed portion Z is a segment set into the disk A, being hinged to it at z, to allow said segment movement to and from the center of the disk A. y

A hook-shaped projection, 0, attached to the segment Z, serves as a step for the spring I), which is fastened to the disk A at a, and serves to press the segment to ard center upon a cam, t, which is circular for three-quarters of its circumference, and has a rising from its center on its other quarter enough to push the segment Z outward to allow but two days to be dropped, leaving twenty-nine days in February each fourth year. To operate this the cam t has attached to it and turning on the same pin fastened in disk A, a fourleafed wheel, S, so arranged that at each revo-' lution of said year-disk A, a leaf of wheel S comes in contact with a stationary arm, W, which is attached to the post Y, carrying said wheel one-quarter round each year, so that every fourth year one day is added, as described.

The dial, Fig. 3, is in front of the works. The spindle of the wheel L projects through said dial and carries a long hand over the face, pointing to figures from 1 to 31 on the circumference of the dial, showing the day of the month.

H is a pawl hanging upon lever B and en: gaging the week-wheel M, which has seven teeth, one for each day, and a retaining-pawl, K. At each motion of the lever B the wheel M is moved one tooth. On the spindle of wheel M is a dial behind the large. dial, show:

ing the days of the week through an aperture in the large dial-Mon. On the spindle of wheel y is another dial, showing the month in a similar manner-May. This monthly dial is operated by means of the wheel 0 having twelve teeth engaged by a hook-pawl, It, upon the leverp, which is connected by a link, 2', to another lever, T, both those levers being supported by the front frame, the fulcrum of the lever T being at it, upon which swings another short lever, V, carrying the pin 1;. These two lovers are connected to operate like a jackknife and blade. A spring being attached to the edge of lever T and passing the joint a, (shown by a dark line,) presses the edge of the pin-lever V. This pin o projects toward the face of the year-disk A, from which twelve pins, 00, stand to engage it as they revolve with the year-disk. The pins 90 and r are flatted to come to a face contact, so that the movement of a single tooth by disk A moves the pin-lever V, and by means of said spring beneath a the levers T and b, pawl R, and wheel '1, so that the dial changes the month on the instant of the presentation of the first day of the same. Then the spring allows further movement of the pin-lever V to permit the pin :10 to pass, the lever T being retained by the pin'N projecting from the front frame. N is another pin limiting the swing of these levers to operate but one tooth of the wheel 9 at a time.

Some of the advantages of my clock-calendar are, first, the facility of setting it to the proper day without opening the works; second, the ease with which it may be taken apart, the front frame and all its dependencies being secured by two screws at the posts X and Y; third, in its being a perpetual calendar, never requiring alteration so long as the clock to which it is attached runs right; fourth, in its general simplicity, causingit to be low in cost and easily kept in repair.

Having thus fully described my invention, what I claim, and wish to secure by Letters Patent, is

1. In a clock-calendar, the communicator consisting of the wheels at and h, spindle r, cam q, yoke g, and spring-clutch 7c l, as described.

2. In a clock-calendar, the lever-B, raised by the clock once at each second revolution of the hour-hand, and allowed to fall of its own weight, carrying with it a pawl, H, which operates the week-wheel, and the pawl O, which operates the year and month wheels as said lever and pawls descend.

3. In combination with the leverB and pawl O, the weighted arm E, lever F, pawl e, and wheel L, as described.

4. The combination, herein described, ot'the pins 00 and o, levers V T spring on lever T, pawl It, and wheel 9 5. The disk or year-wheel A, having three hundred and sixty-five (365) teeth in its circumference, divided into twelve (12) arcs corresponding to months, each are having as many teeth as there are days in its respective month, those arcs representing the months which follow months having less than thirty- 0110(31) days being depressed at one end of the are toward center a distance correspond ing to the depth of as many teeth as the number of days in the previous month are less than thirty-one (31) to allow the pawl to fall in deeper at these periods of time, as and for the purpose stated.-

6. In combination with the disk A, the segment Z, operated by the spring b, cam t, fourleafed wheel S, and stationary arm W, all as and for the purpose specified.
